Hi i have a requirement where i want to encryption the the string like "this is my test application" using a key provided "1DB5-709D-2ADC-5126-AE94-512F-D69D-3E70" and then encrypt the data as below format "8a7d-95b3-1b69-450d-e7af-2adf-3a78-4b68-0481-98f1".

I have tried the normal way of encryption where i am only able to get the output in the below format "23-f4-r2-g3-22-4h".

But i want the format to be as "8a7d-95b3-1b69-450d-e7af-2adf-3a78-4b68-0481-98f1".

At least provide me how i can search in Google,I don't understand how to search it.

Thanks In Advance

That cannot be correct. Your input has 16 bytes (assuming that it is in hexadecimal representation), while your output has 20 bytes - that's not possible.
And your required output format: how are data represented there? I cannot recognise it,"g3" and "4h" are not hexadecimal representations of bytes.

Hi thanks for the reply. for better clarity here is the input n opt that i am getting

the current output with AES enxryption with base64 formatiing is

"41-31-55-A6-DF-BF-D8-78-B3-2D-5A-37-AD-06-B7-E4-20-6C-E6-A7-17-23-10-69-17-AC-40-F3-02-99-6D-C6-25-01-C1-34-39-F3-28-15-B5-FF-8E-E0-B4-E2-B7-F0-61-DA-DF-09-20-39-B7-BC-7F-83-51-50-49-E9-EA-CF-D7-3D-58-DB-BC-FB-B8-F2-97-AF-A6-79-89-0B-C0-7E-9F-9A-36-3D-8A-57-C4-EF-05-08-2A-66-69-83-89-69-B5-47-EA-42-29-15-24-05-D6-D9-74-96-BF-D0-73-13-EA-B2-8D-15-DA-A4-01-BB-7E-94-E9-39-15-CC-9C-4F-DF-8A-B5-18-93-C8-58-C3-10-75-35-73-EA-CE-56-C8"

but where i need the values to be like this
"8a7d-95b3-1b69-450d-e7af-2adf-3a78-4b68-0481-98f1-2a2d-6cf8-ca46-c9da-a1dd-1399-efca-ab55-2e81-e62f-04ee-fac1-77f5-7c79"

and the key ia m using remains the same "1DB5-709D-2ADC-5126-AE94-512F-D69D-3E70".

Hope this information is bit clear.
